With my current trip to Costa Rica coming to a close, I am sharing what I packed for my flights. My travel bag is probably the one and only thing in my life that stays consistently organized. It is important to be both efficient and thorough. Carrying a bag around the airport requires everything to be light weight. Airplanes are usually cold and layers are a must. Plus, with travel plans always in flux, packing other essentials like a good moisturizer, a travel toothbrush, and plenty of snacks can all be a complete life changer.
